The company, founded by Anna Richey and Alla Ouvarova, expects sales to reach £2 million this year. The product is aimed at weight watchers, sports people, cooks, vegetarians and body-builders, as well as those too lazy or in too much of a rush to separate their own eggs.

Sales enjoyed a huge boost in January when Lawson recommended the egg white in her recipe for Cappuccino Pavlova on her BBC programme Nigellissima.

Two Chicks is also an export success story with up to 20 per cent of sales being made abroad. It is sold as far afield as Hong Kong, Thailand and the UAE.
